This invention relates to an apparatus for utilizing solar radiations for therapeutic purposes.

As is well known, certain of the solar radiations, e. g. the ultra-violet rays, are highly bactericidal and it is these radiations which I utilize in my invention.

ket for artificially producing ultra-violet 50 rays for therapeutic treatments but these devices do not, and cannot produce ultra-violet rays of the same bactericidal quality as those found in the solar radiations, and my invention contemplates the utilization of the ultra violet ray of the solar radiations.

The general object of this invention there- .fore is to provide a method and apparatus whereby the suns rays may be used for therapeutic purposes. 1

Referrin againto the awings I have shown my evice for projectmg the suns rays generally at 10 in Fig. 1. This device consists of a base 11 mounted on eastors 12 and adapted to support a hollow vertical standard 13. Mounted on the standard 13 for vertical movement there is a frame 14 having horizontally extending arms 15 and 16 integral therewith and arranged intermediate its length. The frame 14 is adapted to be clamped in any desired vertical position by a clamping screw 14.

The arm 15 is provided with a trunnion 17 on which a yoke 18 is rotatably mounted. This yoke 18 is provided at its ends with bearings 19 and 20 which supports alens frame 21. The yoke 18 is adapted to be clamped in any desired position by a clamp ing screw 17 whicha'cts against the trunnion 17. The yoke 18 is provided with an indi' cating pointer 18 which acts in conjunction with a scored dial 18" mounted on the projectionor arm 15 of the frame 14.

The lens frame 21 comprises a circular body portion 22 having on its outer periphery bosses 23 in which are secured trunnions and 25. The trunnion 24 extends through the bearing 19 of yoke 18 and has on its outer end a pointer 27 which moves over a scored dial 28 on the bearing 19. The trunnion 25 extends through the bearing 20 and is adapted to be clamped in any position by clamping screw 29 mounted on the bearing 20.

On the sides of the body 22 peripheral flanges 30 and 31 are provided. The flange" 31 is of less diameterthan the body 22 and forms a shoulder against which I arrange a rubber gasket 32 which'enga es a lens .34. This lens is retained inlace y a ring 35 which has screw threade engagement with the body 22 and bears against another rubber gasket 36. This construction allows the lens 34 to be readily removed to enable lenses of other sizes and substances to be inserted in the base 22.

The flange 30 is provided with a pair of bayonetjoint slots 37 for retaining a shutter device 38 in the flange 30, which is provided with a pair of bayonet joint pins 39. The

"shutter device 38 may besimilar to a camera shutter of large size and may be operated by a lever 38. The flange 31 is provided with a pair of bayonet joint slots for the reception of a pair of bayonet joint'pins 41 of a cone 42 (see Fig. 4).

The arm 16 of the frame 14 has a rod 43 mounted thereon and adapted to be moved vertically about a horizontal pivot 43 and clamped in any desired position by a clampjunction with a ing screw 44. The rod 43 is provided with an indicating pointer 45 which acts in congradulated dial 46 secured on the frame 14. g

The rod 43 has a circular frame 47 arranged thereon. This frame is adapted to be moved about a vertical pivot 48 and may be clamped in any desired position by a hand screw 48. The frame 47 is also provided with an indicating pointer 49 which acts in conjunction with a scored dial 50 on the link 43. The frame 47 is provided with bearings 51.

Within the frame 47 I arrange another circular frame 52 rovided with trunnions 53 mounted in the'bearings 51 of the frame 47. Mounted on the outer end of one of the trunnions 53 is an indicating pointer 54 which acts in conjunction with a graduated dial 55 secured to the frame 47. The trunnions 53 of the frame 52 are rotatable in the bearings 51 and may be clamped in any desired position by a clamping screw 65.

The frame 52 is rovided with bearings 57 and 58 (see Fig. 35 for rotatably support ing aprism frame 59. The prism frame 59 is provided with bosses 60 and 61 in which are secured trunnions 62 and 63. The trunnion 62 extends through the bearing 57 and has an indicating pointer 64 mounted on its outer end to act in conjunction with a graduated dial 57 arranged on the bearing 57. The trunnion 63 extends through the bearing 58 and is adapted to be secured in any position by a thumb screw 65. The prism. frame 59 is provided with an aperture 66in which a prism 67 is mounted. The 67 is held in lace in the frame 59 by thumb screws 68.

he weight of the frame 14 and the various devices supported by it is partially counterbalanced by a weighted member 69 which works inside of the hollow standard 13 and is connected to the frame 14 by=a cord 70 running overa pulley 71 mounted at the top of the standard 13.

By the provisionof adjustable mounting as previously describedand by using the indicating pointers and dials, the instrument may be readily set for treatment by providing charts which indicate the point at which the various devices should be set for treating various ailments.

The cone 42 as shown in Fig. 4.includes a metal end rim 72 which fits around the flange 31 of the lens base 21 and has secured'to it the pin 41 which engages the bayonetjoint slot 40 of flange 31. Secured to the rim 72 there is an outwardly extending hollow conical portion 73 preferably made of non-inflammable opaque material and provided with a hollow conical removable metal tip 74 at its outer end. The cone 42 is so constructed that when it is used with the proper lens such as 34 (see Fig. 2) the focal point of the'lens will be within the conical tip 74.

For treating various ailments it may at times be desirable to use one or more auxiliary lenses in conjunction with the main lens shown in Fig. 1, and for this purpose I have indicated in Fig. 5 an auxiliary lens stand generally at 75 for supporting an auxiliary lens 76 mounted in a yoke 77 which is supported in a standard 78. The lens 76 is adapted for movement inrelation to the yoke 77 and the yoke is adapted to be vertically moved in relation to the standard 78 and both the lens and the yoke are shown as adapted to be secured in any desired position by clamping screws.

For screening out the undesirable rays I have shown in Fig. 6 a color screen 80 which may be opaque and non-inflammable. This screen is mounted on a rod 80 which is supported on one ortion of a universal joint 82 to allow a wi e range of movement for the screen 80. The joint 82 is mounted on a rod 83 pivotally secured to an upright 84 and adapted to be secured in any desired position relative to the upright by a clamping screw 85. The upright 84 is slidably supported in a standard 86 and may be secured in any desired vertical position by a clamping screw 87 on the standard 86.

As is generally known in the art. the solar radiations are not simply white light, but are composed of the seven primary colors. When the solar radiations are Search Room caused to pass through a lens, as in Fig. ..;u

a and 7 invisible ultraivlolgg dw e ultra-v10 et rays are 0 'fierent wave color spectrum is formed along the line con-.

necting these points, the violet coming to a focus at the point nearest the lens, if convex, and the red at a point farthest therelengths or. variety, and it is these ultra-violet rays which I use for therapeutic purpose.

The different colored rays fare .used for treating different ailments, and to obtain the best results a specific color ray is concenbeam of rays. In this method I project the solar radiations 117 through a lens 118 and screen out the undesirable color rays at the right distance -past the focal point 119 by a screen 120. The undesirable color rays 121 are then projected through a diffusing lens 70 122 into a beam 123. A portion of this beam from. After passin the line of focus the colors s read on The 00 or spec rum as a. 'ilnpingesagainst one side of the object 124 to ma d of 80% invisible infrared, be treated, the remaining rays 125 are allowed or heat rays, 13% visible rays, or white light to pass beyond the object 124 to a reflector 126 from whence a beam 127 is cast'upon the 75 side of the object 124 opposite to the rays 123.

In Fig. 12 I have shown a side elevation of my apparatus set up to accomplish the treatment described in connection with Fig. 8. The solar radiations 128 are projected through the lens 34 to form a beam 129. The

trated on the part to be treated, and to do undesirable color rays are screened out at the this it is therefore necessary to screen out the other colored rays which are not wanted. In Fig. 8 I show diagrammatically the method of treating with the blue violet rays. The solar radiations 100 are projected through a lens 34 to the point (beyond the focal point 102) where the blue violet rays predominate at the outer circumference of the projected rays. At this point the screen is arranged to intercept the undesirable rays and let only the blue violet rays pass. With the form of screen shown in Fig. 6 part of the blue violet rays willnnaveidably be obstructed, but a special screenof more intricate design may be used which will allow all of the blue violet rays to pass while all the undesirable rays will be screened out,

but for the purpose of illustration the screen shown in Fig. 6 will suflice.

After the undesirable color rays have been screened out the blue violet'rays are passed through another lens 104-and are projected onto the portion being treated, which is indicated at 105, the blue violet rays being shown at 106.

In Fig. 9 I show the same method of rojecting and screening the color rays as in ig. 8, and in .addition I provide a lens 108 for spreading the blue violet rays to cause the same to treat a larger area as indicated at 109 on the surface 110 being treated.

In Fig. 10 I show a method of selecting the color rays by means of a prism-111 and projecting the same on the area 112 of the part 113 which is to be treated. In addition to treatment with the color rays, the area 112 is being treated by heat rays 114 which are projected through a first lens 115 and a second lens 116. The lens 116 is constructed to reduce the burning effect which is produced by the lens 115. By treating a patient with both the color and heat rays the bactericidal qualities of the color rays act to kill the injurious bacteria while the heat rays act to cause a better circulation of the blood.

In Fig. 11 1 Show a method of treating an obj ecton both s'ida by employing but a single he shutter 38 is ClOSQfilld the tip 74 is placed over the object to be treated and then the shutter 38 is opened for a predetermined period, and closed again and in this way the concentrated heat rays are allowed to burn the object for a time which may be as sh rt is application I have shown only a few of the methods of using my invention, but it will be understood that various forms of apparatus may be used and that the colorand m heat rays may be projected through as many lenses or prisms as desired to obtain the best resultswithout departing from the spirit of I my invention.
